XCELR8, that's exactly the same stuff that i used, I have yokohama AVS ES100 tires on my RSX and I first made sure they were nice and scrubbed down. Sprayed the tire foam on, and after this rain, my side walls are brown. I'm kinda leary about the westleys stuff b/c i heard if it gets on your paint, it sucks to have that happen. What brands are you talking about zero signal? Thanks for your help guys.
